To all whom it may concern:

Be it known that I, Tomas Bliiiniuai, a subject of the German Emperor, residing at St. Georgen, SchwarzWald, Baden, German Empire, have invented certain new and useful IUIPIOVGIllGlll'S in Calculating-h'lachines,

the number of rotations of the actuating shaft necessary for performing the various steps. In this manner a cam disk is rotated and a locking lever for the coupling or looking mechanisms released, which, during the course of operation of the machine is moved bythe cam disk mechanically out of the path of the lever connected with the coupling and locking mechanisms and thus permits the latter to disengage at the right moment the notched disk, rigidly mounted in well-known manner on the intermediate shaft.

In prior machines the reversing gear shafts for actuating the indicating mechanisms for the individual and total results extend ,right through and are driven direct] y completely flapping over the back bar which carries this mechanism. In the present machine on the contrary the transmission gears are mounted on two shafts which are located' axially one behind the other and are under the influence of other shafts which are rotated by the stepped. cylinders; in this inanncr the mechanism for indicating the total result can be disengaged without the bar carrying this mechanism having to be fiapped over and the mechanism thus exposed. l urthermore, to prevent wrong calculations such as not infrequently occur with prior machines, owing to self-motion of the centrifugal masses, through turning of the locking disks, special locking devices are provided oii'the pawls of the shafts which are rotatedby the steppedcylinders, which devices admit of rotation of the ratchet mechanisms independently of that effected by the stepped cylinders, for the purpose of transference from a lowerQto a higher denomination.

My invention is illustrated in the accompanying drawings, in which- Figure 1 is a front elevation of the actuating mechanism, Fig. 2 a plan, theactuating shaft being uncoupled, and Fig. 3,1 plan with actuating shaft coupled. Fig. 4-is a. side elevation and part section. Fig. 5 is an elevation, partly in section, showing the crank for hand actuation. Fig. 6 is a plan of Fig. 5. Fig. 7 is a vertical section through the machine seen from the front,

the section being taken just behind the front frame plate, through the mechanism shafts and stepped cylinders, in two prominent positions. F 1g. 8 is a 'lan of Fig. 7 with the bars pushed to the right hand side. Fig. 9 is a side elevation, the actuating device and a portion of the mechanism shafts and stepped cylinder being omitted.

The intermediate shafting for transinit ting motion consists ofv two shafts 3, 4: provided with clutch halves 1, 2 respectively. 3

The clutch half 1 rigidly mounted on the shaft 3, while the clutch half 2 slides on the shaft 4', so that the two shafts can befcoupled and uncoupled as desired. The shaft 3 is driven by the electric motor, which is thrown in simultaneously on a level-{being actuated to cause mutual engagement of the two i The shaft 4 is connected 'with the actual operating shaft 5 of'the nia-.

clutch parts 1, 2.

chine (which can equally well be actuated by" means of a crank handle) by a spur wheel 6. Onthe shaft i there is also mounted a worm 7, which on gages with a wormwheel 8 whose boss is loosely mounted on a vertical pin andwhich carries above a cant disk 10 (Figs. 1

and 2). wheel 8 by a star wheel 9 being secured to the top of the bo'ss of the wheel 8 and a de-- tent 9 pivoted to the lower face of the cam The latter is connected with a l disk '10 and being held in engagement with the star wheel by means of a spring. The cam disk 10 in this manner normal y partakes of the rotary motion of the worm wheel 8, but can nevertheless be adjusted (that is to say turned) relatively to the worm Wheel 8 by the en'iployment of suiiicient force to overcome the power of the spring of the pawl 9*. On the upper 10 and rigidly connected with it is a toothed wheel 11, with which there engages a i'nutl latcd gear wheel 12, which can be turned by means of a pointer l l moving over a dial 13 (Figs. 2 and The dial is marked with the numerals l- IX and the pointer 14: is

set to the corresponding figure, depending upon the number of rotations to be given. to the actuating shaft '5 for the particular calculation. The rotation of the pointer 14 results in a rotation of the cam disk 10 also,

the extent or angle of rotation of the latter depending upon which of the 'nine figures the pointer is set to.

On rotation of the disk 10 its cam releases a spring actuated lever 16 pivoted at 15, whose nose 17 bears laterally against a fork of a bent lever 18 which serves to shift the slidin clutch half 2; on the lever 18 being turns to the left hand the nose 17 snaps behind it and locks it, preventing its movement in backward direction. The rotation of the worm shaft 1 for operating the main shaft 5,

effected by the coupling operation, results in the rotation of the worm wheel 8 with cam disk 10. The cam of this disk thus moves in accordance with the motion of the disk into the initial position, and in doing so it strikes the elevated end of the locking lever 16 (Fig. 1) and so turns it that the nose 17 leaves'the bent lever 18 and thus releases the latter.

The vertically directed, forked end of the lever 18 is slotted to receive the pins of-a col- .lar located in the groove of the clutch half 2, and serves for shifting this part. The

other arm of this lever 18 is connected with a lever 20, pivoted at 19, whose longer arm projects upwardly out of the top plate of the machine and terminates in a finger-knob 2]. The lever 20 presents-a projection 22 of insulating material against which there bears a spring 23, which has the tendency to hold the lever 20, bent lever 18, and clutch half 2 in the full line position (Fig. 1). In

this position the locking tooth 24 of a bridge piece secured to the forked arm of the lever 18 enters a notch provided in a locking disk 25 (Figs. 4 and l), which is secured to the The shafts 4 andv 5 are thus shaft 5 for the purpose of making some parjlicular (ftllciililllflll has to be turned for in-' stance four times, the pointer 1.4 (which can i be turned from above the cover plate ofthe face of the cam disk machine) must be turned to the mark IV of the dial 13 ({Fig. 3). This adjustment causes the cam di 10 to be turned from its position shown in Fig. 2 into that shown in Fig.

8. The locking lever 16 initially held by the 'cam disk 10 will thus be released and its nose 17 will bear against the side of the bent lever 18. After the pointer 14 has been set the lever 20 is operated by depression of the knob 21. On the lever 20 being thus depressed the spring 23 will close a circuit containing the electric motor, so that the latter will be started and the shaft 3 thus coinmence to rotate. .011 the lever 20 and the bent lever 18 with -the sliding clutch art 2 arriving in the dotted line position ig. 1,

the nose 17 and the locking lever 26 will snap behind the bent lever 18 (Fig. 3) and will obstruct return of the latter; and at the same time the locking tooth 24: will leave thenotch in the locking disk 25 and thus release theworm shaft 4. The machine thus operates, the cam disk 10 and the pointer 14 returning to their position of rest (Fig. 2) according to the number of turns 0 the worm. The other parts arrive in this position in the moment in which the actuating shaft 5 has executed four rotations. At this moment however the lockin lever 16 being turned by the cam of the disllO will release the bent lever 18, which under the indirect influence of the contact spring 23 will turn to the right, whereby the shaft 4 will be uncoupled, while the lockin tooth 24 will enter the roove in the disk 25 and retain the shaft 4 in a definite position.

In the event of the calculating machine having a crank handle-instead of being 0 ing the disk 25 of the shaft 1. The shaft 5 I is in this case actuated in well known manner by means of a bevel gear 26 (Figs. 1, 2, 5, right hand) from the crank shaft 27. For rotating the crank shaft 27 the latter is provided with a square head to receive a sleeve 29 (Figs. 5, 6) having a ratchet wheel 28 and adapted to receive the crank 30, which has a spring controlled pawl 32 pivoted by means of a screw 31 and engaging with the ratchet'wheel 28. The crank can thusbe turned in a direction contrary to that of the arrow (Fig. 6) without the shaft 27 being I affected, the latter only being rotated when the crank is turned in the direction of the said arrow. Backward rotation of the crank is necessary in order that the crank in the event of its standing at the completion of a calculation above the knobs 33 of the slides (Figs. 5, 6) may be turned back for instance into the dotted line position (Fig. 6) so as to admit of unobstructed manipulation of -the knobs again. The arrangement might adn'zitof backward rotation in the already described manner.

The shafts carrying the stepped cylinders 36 (that is to sayrollm's with teeth of iniireasing length) are driven ll'Olll the shaft by ;n eans of the bevel gear Ill and pass right through the machine, being provided with sliding teeth 38, secured to the cylin- .driczt segments 37, for trims-'l'erring to a higher denomination; they also :arry collars 39 having projections. The cylindrical se inents 37 serve to set the .lockin disks 4O r1 b 7 \Vhiull with 'the wheels 41 for the t 'ansterone behind the other.

once to a higher denomination are secured to reversing gear shafts 4-2, 43 mounted axially These shafts 42, 4-3, also carry the necessary sliding reversing gears let for driving the indicating mechanism. The reversing gears of the shafts 42 (Fig; 9) can in well known manner he brought into engagement alternately with the bevel gears 45 of an indicating mechanism which is mounted on a pivotal and sliding bar 4-6 and serves for indicating the various iinlividual results The reversing gears 44' of the shafts 43 act in the same manner on the bevel gears 17 of mechanism for indicating the total results, which mechanism is mounted on a-pivot'al and slid ing bar 48. he reversing gear shafts 42, 43 are driven by means of the rotary motion of the shafts which at the front end carry thetoothcd wheels (Fig. 8), which are capable of sliding and engage with the teeth For this purpose spur wheels 51, 52 are mounted on the shaft 49 in the plane of motion of the wheels 4]. These spur wheels 51, 52 engage with wheels 41. by means of intm'nwdiate wheels 5?. 'lhey are also provided with crown teeth with which there engage the crown toothed sleeves 54, 55 which are capable of sliding and are controlled by springs. The crown toothed sleeves 55 are provided at one end with a shoulder 56 (Figs. 8. 9) and can also be moved forward with positive motion by a rod 57, that is to say, brought out of engagement with the crown teeth of the wheels The wheels 51, 52 are loosely mounted, so that when the sleeves are disengaged from the crown teeth of the wheels 52 and the shafts 4t!) rotated, the reversing gear shafts remain at rest. In this case by operating the calculating inaehine it only the shafts 4-2 and with the aid oi. their reversing wheels 4-4 thenmcchanism on the bar at) that will be operated for the purpose 7 of indicating the individual results.

In order to prevent sliding of the crown wheel sleeves 54, 55, and thus avoid possible rotation of the wheels 41, 53,

shafts 42, 43 through. centrifugal force of the parts 01' the mechanism at the moment in which the segments 37 for a short tune are out of engagement with the disks 40 (l ig.

7 left handithere are mounted on the axes 51., 52 andjthe.

of the intermediate wheels 53 pawls 58 which engage behind the sleeves 54, 55. The pawls have arms whlchare controlled by springs (30 and project into the path of the pins til, (32 of which those marked 62 project lromdisks 63' (Fig. 9) secured to the shaft 35, while those marked 61 project from the rear end oi? the stepped. cylinders 36 (Figs. '7, S, 9). At each rotation of the stepped cylinders 36 with. their shafts the arms 59 of the pawls 58 are pressed back by the pins (Si, 62, and the pawls temporarily release the sleeves 541-, 55 otherwise prevented from shitting by them. This release occurs at the moment 111 whlch:transference to a l'ngl'ier denomination takes place (Fig. 7 right hand) and. is requisite in order that this transference may take place independently in each of the two mechanisms. This however is only possible if at the period. in which the wheels it. are advanced through the dis' tance otone tooth. by the teeth 38 (Fig. 7 right haml)-which rotation is also made by the intermediate wheels 53 and the wheels 51, 52---if the sleeves 54, 55 do not engage with the crown toothed Wheels 51, 52 that is to say can slide forwardly. This is necessary in order that the shafts 49. which are coupled by the sleeves 54, 55 of the two mcclh anisms, on completion of the transference to the higher denomination may remain. at rest in the one mechanism. To disengage the indicating mechanism for the total result, that is to say bring the sleeves 55 out of the province of the crown teeth of the wheels 52, the pawls which preventv these sleeves from sliding must be swung back. For this purpose lugs (54 (Figs. 8 9) are furnished on the bar 57'which serve'i'or disengagemeiit of the sleeves 55 by hearing against their shoulders 56. These lugs 64.011 sliding of the bars toward the left in big. 8 strike the 511711559 ofthe pawls 5S and by raising them from the necks of the sleeves cause release of the latter. In this manner the barf/7 can be n'i'oved for *ardlongitudinally sleeves 55 with it. p

The connection between the bars 46, 48 is constituted by a. slide 65 forked at one 'end and sliding with friction on the bar 4 8. The full line position of the slide 65 is that when the bars are coupled. The fork part of the slide engages theneck' of a stud (36 (Figs. 8, 9) secured to the front bar a6.

The bars are operated by means of the knob 67 which projects from the bar 46. For this and carries the.

purpose the bar 46 is first moved by means of the knob 67 into the dotted line position (Fig. 9), whereby this bar is disconnected from the frame plate and the bar 48 is turned simultaneously so that the bevel wheels 45), 47 of the two indicating mechanisms are disengaged from the reversing gears 44, whereupon the bar can be slid alon to the rows of figures in question. The ares of the individual results appear in the apertures 68 of the front bar 46, and the rows of figures of the sum'ap ear in the apertures 69 of the rear bar 48 igl 8).

To uncouple the bars the slide 65 is moved back by means of the knob 70 from the full line into the dotted line osition (Fig. 8). This shiftin must be e 'ected when only the front indicating-niechanisni for the l1ldividual results is in use, while the totalizing mechanism remains at rest. The front bar, for the purpose of overcoming the connection and uncoupling of the gears 45, 44 can then be turned, 'slid alon and fiapped down for effecting the require operation, Without the rear bar being carried with it.

lihe operation of the apparatus is as follows :buppose the individual results and the total sum are to be indicated, that is to say both indicating mechanisms are to be used, which is done by actuation of the shaft 5. The stepped cylinders 36, owing to their engagement with the gears '50 Fig. 8) in question and previously adj iste will turn the shafts 49 through a certain angle. The sliding crown toothed sleeves 54-, 55 which engage the crown teeth of the wheels 51, 52 cause these, wheels to be rotated, and they transmit their rotary motion to the reversing gea r shafts'43, 43 by means of the intermediate wheels 58 and the wheels ll for transference to a higher denomination. From these shafts the indicating mechanism is actuated by rotation of the bevel gears 45, 47 which mesh with the reversing gears 44. The transference to a higher dcnoinina' tion, which is done in well known manner with the aid of the teeth 238. can be ell'ccted in the two mechanisms llltltptlnltlllly of each olhcr. since the crown toolhedsleeves 54, 5:") on rotation of the wheels ll and thus also of the. wheels 51. fr. can remain out of engagement with lllt latter. that is to say with the crown teeth ol these wheels. The bars 46,48 are coupled together it' both indicating mechanisms are to be used. and the coupling slide 5 will occupy the full line position (l igs. 8, 1)), so that on actuation of the bar -l-ti by means of the knob (ET, the bar 48 will be. moved also and accordingly both individual results and the total result will be indicated. ll on the contrary the totalizing mechanism of the bar 18 is to remain. at resl, so lhal. only the individual results are to be indicated, the bar 57 by rotation of a lever in connection with it "but not shown in the drawing, is first moved toward the left for the purpose of lifting the pawl 58 out of the sleeve (Fig. 8) and then moved forwardly parallel with itself (Fig. 9) to cause disengagement, and the slide (35 of the bars 40, 48 is pushed back into the dotted line position (Fig. 8) to uncouple the latter. The gear wheels 52, 53, 4t, 44, 47 and the actuating shafts 43 of the totalizing mechanism thus remain at rest during operation of the machine. The

operation of the indicating inechanism for the individual results is'ell'ected in the man.- ner already described, the bar 46 being capable of being shifted as required independentl y of the bar 48 which remains at rest.
